A: The influence of retrieval strategy on retrieval effect.
(Suzhou Institute of Technology, Jiangsu, Suzhou)
On the basis of analyzing retrieval problems, retrieval strategy is to determine the logical relationship among retrieval database, retrieval words and retrieval steps scientifically. In our retrieval process, paying attention to retrieval strategy can improve our retrieval quality and facilitate our retrieval. The retrieval strategy has a great influence on the retrieval effect, so more retrieval strategies should be used in retrieval.
Keywords: search strategy, search effect information search
1. The concept of retrieval strategy
The so-called retrieval strategy is to determine the logical relationship between retrieval database, retrieval words and retrieval steps on the basis of analyzing retrieval questions.
2. The link of retrieval strategy
2. 1 Define project requirements and select database
The first step in the retrieval process is to clarify the requirements of the subject. If there is an error in the first step, the correctness of the final retrieval results will be out of the question.
(1) Analyze the purpose of topic retrieval
(2) Clarify the subject range and professional aspects involved in the topic: Clarify the main subject range, related subject range and interdisciplinary subject range involved in the topic, and select according to the subject collection range of the database.
(3) Requirements for document novelty: If the requirements for document novelty are high, it is necessary to choose a database with short data update cycle and high speed.
(4) Users' requirements for retrieval completeness and accuracy: In order to meet the requirements of retrieval completeness, various databases need to be investigated, and in order to meet the requirements of accuracy quickly, the database with the most specific subject range should be selected.
2.2 Theme analysis
After defining the retrieval requirements, it is necessary to analyze the specific content of user topics, which is the key to correctly select retrieval words and logical operators, and will determine the quality of retrieval strategies and affect the retrieval effect.
3. The influence of retrieval strategy on retrieval effect
(1) can speed up retrieval and save retrieval time.
(2) The correct retrieval strategy can enable us to retrieve information more comprehensively.
(3) The correct retrieval strategy can help us to retrieve information more pertinently, but the retrieved information is more accurate.
4. Problems that should be paid attention to when formulating retrieval strategy.
If you are unfamiliar with the topic, you can use key documents to confirm vocabulary and clarify concepts. It is suggested to avoid choosing too extensive or vague vocabulary retrieval, and store and reuse the same concepts and retrieval strategies to save retrieval time. When searching, we can not only use the selected search words, but also use the index book, title list or related words automatically provided by the system to increase the search results.
summary
Retrieval strategy plays an important role in our retrieval. Making retrieval strategy is a comprehensive knowledge and skill, and it is also an experience. Mastering this skill and experience will achieve better retrieval results in the retrieval process. We should strengthen the training of retrieval strategy. Starting from the following aspects: ① the clarity of the subject; ② Analysis of retrieval topics; ③ Master the characteristics and functions of the database and its system; ④ Skills of writing logical retrieval; Strengthen the training of retrieval strategy; Improve the retrieval effect. The retrieval strategy has an important influence on the retrieval effect, which directly determines the relevance of the results. Correct and effective retrieval strategy can save us a lot of precious time and really get twice the result with half the effort.

The second part is the basic knowledge of literature retrieval.
Short answer questions:
1. What is literature? What types of documents are formed according to the depth of document processing?
A: Literature is a carrier that records human knowledge by means of words, figures, symbols, audio-visual images, etc., or is understood as knowledge solidified on a certain material carrier. It can also be understood as the floorboard of all social historical materials in ancient and modern times. Now it is usually understood as the sum of books, periodicals and other publications.
Literature can be divided into four levels according to the depth of processing, namely, first-class literature, second-class literature, third-class literature and zero-class literature.
2. International standard book number
Answer: ISBN: The International Standard Book Number (ISBN for short) is the code of books or independent publications (except periodical) commonly used in the world.
3. Accuracy ratio
A: Precision is an index to measure the signal-to-noise ratio of the retrieval system, that is, the percentage of detected related documents to all detected documents. Generally expressed as: precision ratio = (relevant information retrieved/total information retrieved) x 100%.
4. Briefly describe the types of retrieval languages. A: Search languages are classified according to different characteristics. According to the characteristics of literature information, it can be divided into: the language that describes the characteristics of information content and the language that describes the external characteristics of information; According to the arrangement system of retrieval tools, it can be divided into: classification language and topic language; According to the types of vocabulary, it can be divided into: keyword language, unit word language, headline word language and narrative word language. According to its specification, it can be divided into: artificial language (normative language) and natural language (non-normative language); According to the lexical collocation of retrieval languages, it can be divided into the first group of languages and the second group of languages.
5. What are the three retrieval tools that academic circles call evaluative, and what are the differences in the scope of their literature collection?
A: The three retrieval tools that academic circles call valuable are SCI (scientific citation index), EI (engineering index) and ISTP (scientific conference proceedings index).
SCI is an important periodical abstract index database in natural science field. It can be used to retrieve important academic achievements in mathematics, physics, chemistry, astronomy, biology, medicine, agricultural science, computer science, material science and other disciplines.
